SHEET COLLECTING AND DELIVERY MECHANISIVI.

SPECIFICATION forming part of Letters Patent No. 505,442, datedseptember 2e, 1893.

Application filed March 3, 1892. Serial No. 423,561. (No modeLl To allwhom it may concern:

Be it known that I, LUTHER C. OROWELL, a citizen of the UnitedStates,'residing at Brooklyn, county of Kings, and State of New York,have invented certain new and useful Improvementsin Sheet Collecting andDelivery Mechanism, fully described and represented in the followingspeciication and the accompanying drawings, forming apart of the same.

The object of the present invention is to i provide a simple andefficient delivery mechanism by which a series of sheets may be,collected from the web and delivered without folding at a high rate ofspeed, and further to provide a construction in which the collectingcylinder delivers directly to a iiy or equivalent final deliverydevices.

In the construction embodying my invention the collecting cylinder formsone of a pair of cutting and collecting cylinders, and the co-operatingcutting cylinder may be so constructed and positioned as to co-act withthe collecting cylinder to advance the sheets after they are released bythe sheet holding pins, but I preferably provide an independent feedingroll for this purpose, and prefer- ,ably mount this roll So as to yieldas successive sheets are collected upon the cylinder, thus securing theproper feed of the sheets irrespective of the increase of surface speedof the sheets as they are collected upon the cylinder.

I secure certainty in the delivery at high rates of speed by providingthe collecting cylinder with strippers co-acting with the sheet holdingpins to throw the sheets off the pins and away from the cylinder asufficient distance to insure their reception by the fiy or otherdevices co-operating with the cylinder, and I have devised andpreferably use a collecting cylinder of an improved constructionemploying pins and strippers moving together in delivering the sheetsfrom the cylinder, in which the pins are actuated positively andindependent of theengagement of the pins by the strippers, a certain andsmooth action of the parts being thus secured ata very high rate ofspeed and the wear upon the pins and grippers being reduced so that thisaction may be maintained for a longtime.

My invention, therefore, consists broadly in a sheet collectingcylinder1 and dev ices coacting therewith to sever sheets from the weband deliver them directly to a fly or equivalent delivery devices and invarious constructions and combinations of parts in a machine embodyingthis invention, and in various improvements of general application incollecting cylinder constructions whether delivering directly to iinaldelivery devices or not, all of which will be fully described in thefollowing specification and pointed out in the claims.

It is evident that the construction of the other parts of the deliverymechanism with which the parts embodying my invention coact may bevaried widely and that mechanisms of different forms may be used foractuating the pins, strippers, and tly. In the accompanying drawings,however, I have shown the delivery end of a machine embodying myinvention, which forms a very simple and efficient construction capableof operating at a very high rate of speed, and the invention will now bedescribed in detail as embodiedin this machine.

Referring to the accompanying drawings:- Figure 1 is a side elevation ofthe delivery end of a printing machine. Fig. 2 is an end elevation ofthe same the small parts being omitted for clearness in showing thegeneral construction. Fig. Sis a side elevation of the collectingcylinder, the operating cam being shown in section. Figs. 4, 5, and 6are diagrammatic sections taken inside the frame, showing the parts indifferent positions during the operation of collecting and deliveringsheets. Figs. 7 and S are sections on the line 7-8 of Fig. 3 lookingrespectively tothe left and right in said figure. Fig. 9 is a section onthe line 9 of Fig. 3 looking to the right. Fig. 10 is an end viewlooking to the left in Fig. 3. Fig. 11 is a section taken inside theframe showing the end of the cylinder as in Fig. l0, but with the partsin a dierent position and showing the cam for operating the pins andStrippers. Fig. 12 shows a modification.

Referring to said drawings UA, B, are the opposite side frames of themachine, C the IOO last impression cylinder of the printing mechanism, Dthe collecting cylinder, E the cutting cylinder co-acting therewith tosever the sheets, and F the fly by which the sheets are delivered fromcollecting cylinder D. The web is shown as led from the impressioncylinder C to the collecting cylinder D over and under a pair of feedingrolls 10, 11 so as to secure the proper feed of the web to be seized bythe pins of the collecting cylinder, but it will be understood that anyother suitable arrangement may be used for this purpose.

The collecting cylinder D is out away for the pins and strippers, andpreferably consists of a series of disks 12 mounted on the shaft 13 withbars 14 extending the full length of the cylinder and between the disksso as to form the cutting groove 1 co-operating with knives 2 of thecutting cylinder E to sever the sheets. The cutting cylinder E is shownas twice the sizeof the collecting cyl-V inder D and as provided withtwo knives 2, but it will be understood that the cutting cylinder may beof the same size as the collecting cylinder D, if preferred.

Between the disks 12 are mounted the sheet holding pins a. and strippersb by which the collected sheets are delivered from the pins to the fly.The pins and strippers may be of the usual construction, the pins beingset at the proper angle to seize and hold the successive sheets, and thestrippers being formed of fingers preferably made of thin rigid metaland provided at their outer' ends with openings through whioh the pinsextend. The pins d are mounted on a shaft 3 extending through the disks12 forming the collecting cylinder, which shaft carries at one end acran-k arm 4 connected by a link 5 to a crank arm 6 on shaft 7 whichcarries the strippers band is mounted in the disks 12. The strippers bcarry at one end a crank arm 8 provided with a bowl which runs in a camplate 91 mounted to rotateon shaft 13 and provided with a gear 15 bywhich it is driven. It will be seen that by this construction, as theshaft 7 vis rocked to throw the strippers h outward and carry the sheetsfrom the pins a, the pins are simultaneously rocked upward toward thestrippers so as to bring them into position radially to the collectingcylinder D, thus following the motion of the sheets as they are pressedoff the cylinder by the strippers b and permitting them to be readilyremoved without danger of tearing the sheets. The movement of the pins)and strippers relatively to each other are so timed that the pins are inthe same position relatively to the strippers during every portion oftheir movement and the strippers need not be slotted but simplyperforated for the pins, as shown in Fig. 3. It will be understood,however, that the strippers may be slotted and the parts not soaccurately adjusted, but the operation of the construction is muchbetter with this accurate timing of the parts. By actuating the pinspositively and independently of the engagement of the pins by thestrippers, I am enabled to obtain a smooth and uniform movement at veryhigh rates of speed and there is practically no Wear between the pinsand strippers, so that these parts will stand such speed for a long timewithout renewal.

In front of the collecting cylinder D and above the fly Fa feeding rollis mounted,this roll being cut away opposite the pins a and strippers band formed preferably, as shown, by a series of disks 16 mounted in arms17 carried by the shaft 18 and spring pressed through crank arm 19 byrod 20 slidingin lug 21 on the frame and pressed by spring 22 asusualinsuch constructions. Thisfeedingroll co-acts With the collectingcylinder D between the pins a and strippers b to feed the sheets forwardafter they are received from the pins and thus secure the delivery ofthe sheets to the ily F. The shaft 18 and parts carried thereby arepreferably mounted in brackets 23 adjustably secured to the frame byslot and bolt 24, as shown, or in any other suitable manner, so as topermit the adjustment of these parts to secure the best operation ofdisks 16 in combination with the collecting cylinder D, and inaccordance with the number of sheets to be collected. Vhile this springpressed feeding roll is preferably used, it will be understood that itmay be omitted and the cutting cylinder E be constructed to co-act withthe cylinder D in feeding the sheets, as shown in Fig. 12,the cylinderEbeing preferably provided with rubber bands c, as shown, or equivalentdevices, to secure the feeding of the sheets, but this construction isnot satisfactory when many sheets are collected at a high rate of speed,while the use of the spring pressed feeding roll secures the properfeeding of a large number .of sheets, and by adjusting the position ofshaft 18 the exact pressure required may be secured with any number ofsheets. It is not absolutely essential that the feeding roll should bespring pressed, if the number of sheets is not to be varied, as the rollmay be set at just the right distance from cylinder D to secure thefeeding of the sheets when released by the pins, but the constructionshown is much preferable and aids materially in attaining a highdelivery speed. With a series of independent disks 16 forming thefeeding roll, and made adjustable on their supporting shaft by setscrews, as shown in Fig. 2, or otherwise, it is possible also to adjustthe disks so as to bear upon the margins of the paper thus avoidingoffset, and as the cylinder E does not touch cylinderD, all offset fromthe collecting cylinder is avoided even at high rates of speed. Themachine is shown as adapted to deliver two series of papers side byside, and the disks 16 as set accordingly to engage the center and sidemargins.

The fly Foonsists of the usual series of iingers mounted on a rock shaft25 actuated to deliver the sheets by a bar 26 sliding in lug 27 on theframe and secured to crank arm 28 IOO IIO

on shaft 25, this bar 26 being spring pressed by spring 29, as usual insuch constructions.

The shaft 25 is rocked in the opposite direction to return the fly Fagainst the tension of spring 29 by a rockinglever 30 connected to crankarm 31 on shaft 25 byan adjustable pitman 32, this lever 30 beingprovided with a bowl 33.which runs upon a rotating cam 34 carried byshaft 35 mounted in the frame B.

Ihe operating parts of the machine may be driven by any suitable meansand from any part of the machine. In the construction shown, the shaft35 is driven from the impression cylinder C by intermediate 36, and gear37 and pinion 38 mounted on a stud in frame B, the pinion 38 engaginggear 39 on Shaft 35, these parts being so timed that the shaft 35 .andcam 34 make rotation for rotation with the cylinder C. The collectingcylinder D is driven from gear 37 byintermediate 40 meshing with gear 41on shaft 13, and the cutting cylinderE is driven directly from the shaft13 by gear 42 meshing with gear 41, these parts being so timed that thecollecting cylinder D makes four rotations to one of impression cylinderC and shaft 35, so that four sheets are collected uponthe cylinder D toeach rotation `of the iiy. It is necessary that the cam 8 be driven at ahigher rate of speed than the collecting cylinder D so that the fingersa and strippers b will be actuated to deliver the sheets once to eachfour rotations of the collecting cylinder D, and this cam is driven fromthe shaft of cutting cylinder E by gear 43 on said shaft inside theframe A engaging gear 15 on .the cam disk, these gears being so timedthat the cam disk makes about five rotations to four of the collectingcylinder. The feeding disks 16 are driven directly from shaft 13 of thecollecting cylinder D by gears 44, 35.

The operation of the construction will be understood from a briefdescription in connection with the drawings. As the web is fed by `rollsl0 and 1l to the collecting cylinder D the web is seized by the pins atthe leading end of each sheet as the pins pass the feed roll 11, asshown in Fig. 6, and each sheet is severed by one of the knives 2 of thecntting cylinder co-acting with groove l of the collecting cylinder allin the usual manner. Vhile the number of sheets for which the parts areadjusted are being collected upon the cylinder D, the pins a andstrippers h remain stationary with the pins projecting forward in theline of movement of the collecting cylinderD at an angle to the radiusof the cylinder so as to seize the sheets properly, and the strippersare withdrawn inside the cylinder during this movement, the bowl oncrank arm 8 of shaft 7 riding upon the concentric portion of the cam9and all the parts being in the position shown in Figs. 3 and 5 to 10. Inthe present case the number of sheets collected to each delivery arefour, but itwill be understood that this number may be varied as desiredby changing the timing of the parts as usual in collecting cylinderconstructions. 1

When the four sheets are collected and the pins a and strippers h havepassed the feeding roll 16 so that the leading ends of the sheets may bethrown outward from the cylinder, the cam 9 in its more rapid rotationthan the cylinder D has caught up with the latter and the bowl on crankarm 8 now passes into the depressed portion of the cam 9 and thestrippers b are thrown outward from the cylinder so as to force theleading ends ofthe sheets off the cylinder, and at the same time by theconnection between shafts 7 and 3 the latter shaft is rocked to move thepins so as to follow up the strippers as the sheets are forced outwardover the pins, the easy delivery of the sheets from the pins @being thussecured and all danger of tearing the sheets avoided. This position ofthe parts is shown in Figs. 4 and 11, the ends of the sheets having beenjust thrown off from the cylinder so as to be carried outward sufcientlyto be received by the iiy F. In this position of the parts, the fiy hasjust been returned against the pressure of spring 29 by the action ofcam 34 on the bowl 33 and is now in its innermost position, as shown inFig. 4. The collected sheets released from the.pins are now advanced byfriction between the collecting cylinder D and the disks 16, and thesheets are fed downward in front of the stationary fly F, as shown inFig. 5, the leading end of another sheet having been meanwhile seized bythe pins ct. As the sheets pass downward in front of the fly, the bowl33 is just about to pass off the raised portion of cam 34 so that thespring 2O may operate to throw the fly downward to deliver the collectedsheets, this position being shown in Fig. 5. One series of collectedsheets having been thus delivered the fly is again returned to positionby the action of cam 34 on bowl 33 and meanwhile the collecting cylinderD is collecting another series of sheets, as shown in Fig. 6, and thusthe operation is repeated.

It will be understood that short stationary guides may be used betweenthe ily and collecting cylinder if desired, and such a construction isintended to be included under the terms delivering directly to the fly,as the equivalent of the construction shown. Such` IIO a guide, however,will generally be found uni which the delivery of the sheets depends isslight and the efficiency of the mechanism not substantially impairedthereby, so that great` durability is combined with high capacity.
